*Slight spoilers* I fucking love these two, but if they "died" the way I think they did (at Monument Island), then does that mean that Ty Bradley is unstuck in time and space too? Oh god I hope so. I would love to think in my head canon that he's stumbling through the universe, seeing how life gets better for all of the races, while still being a little grumpy about it.
